SAVAGE Modeling Analysis Language (SMAL)
Curtis Blais and Terry NorbratenMOVES Institute
Naval Postgraduate School
Objective
Better methods are needed for improving the fusion and presentation of data required by the battlespace Commander. One method is to develop a 3D representation of the battlefield. Increasing the speed and ease of construction of 3D scenes to augment 2D displays via “autogeneration” is key to this next step of battlespace visualization (BSV).
Background
Developed by LCDR Travis Rauch, USN
Rauch, T. M., “Savage Modeling and Analysis Language (SMAL): Metadata for Tactical Simulations and X3D Visualizations,” Master’s Thesis, Naval Postgraduate School, Monterey, CA, March 2006. http://theses.nps.navy.mil/06Mar_Rauch.pdf
Application to research projects in the Scenario Authoring and Visualization for Advanced Graphical Environments (SAVAGE) Research Group (SRG) in the MOVES Institute
Purpose
Strategy for identifying tactical, physical and simulation-oriented metadata for vehicles, terrain and entities in virtual environments (VEs)
Collects and organizes information necessary to create and populate a 3D virtual environment
Equivalent XML and X3D representations for SMAL are defined
Related XML-Based Languages
• Military Scenario Definition Language (MSDL)
• Joint Command, Control and Communication Information Exchange Data Model (JC3IEDM)
• Battle Management Language (BML)• Tactical Assessment Markup Language
(TAML)
Supporting Data and Metadata Standards
• Dublin Core Metadata Initiative (DCMI)• Resource Description Framework (RDF)• Web Ontology Language (OWL)• Geography Markup Language (GML)• Joint METOC Broker Language (JMBL)• Building Informational Model (BIM)
SMAL Usage
